Abstract The mechanism of action of α- l -arabinofuranosidase, α- l -rhamnopyranosidase, and β- d -glucopyranosidase on p -nitrophenyl and grape monoterpenyl disaccharide-glycosides has been studied. First, the (1→6) linkage is cleaved by either α- l -arabinofuranosidase or α- l -rhamnosidase, and arabinose, rhamnose, and the corresponding monoterpenyl β- d -glucosides are released. Subsequently, liberation
